0 all whom it may concern Be it known that I, ARTHUR A. JOHNSON, a citizen of the United States, residing in borough of the Bronx, in the county of the Bronx, city and State of New York, have invented certain new and useful Improvements in Combined Type-Writing and Coinputing Machines, of which the following is a specification.

This invention relates to combined typewriting and computing machines.

To obtain the orosstotals of numbers typewritten in different columns, it has been the custom to employ a cross-totalizer, which has usually been provided with means to connect and travel intermittently with the typewriter carriage.

For this purpose, tappets have been provided on the typewriter carriage, for picking up the cross-totalizer at intervals.determined by the locations of the tappeis, and, for convenience, these tappets have been formed upon the tabulator stops which are customarily used for jumping the carriage to a computing zone.

The tabulator stops are also employed for positioning the carriage in non-computing zones; and the non-con1puting zone-stops have not been provided with the tappets for controlling the cross-totalizer.

Hence, it has heretofore been found necessary to provide two kinds of tabulator stops in a machine of this character, one kind for computing zones, and one kind for 11oncomputing zones; and it has also been necessary for the operator to use great care to place the right stop in the right place upon the typewriter carriage.

In other words, the ordinary tabulator stops on the typewriter carriage could not be used for reciprocating the cross-totalizer during the movement of the carriage, but were specially made with lugs for this pur- 'pose, and it was necessary for the operator to see that the proper stop with the lug was placed in proper position on the typewriter carriage for a computing zone.

The present invention provides means whereby all the stops may be uniform, whether used for one purpose or the other, thus avoiding care and time occupied in selecting and placing the stops. To bring about this result, the connections between the cross-totalizer and the carriage, which are normally out of position to be engaged by the tabulator stop, are moved into effective positions as the typewriter carriage enters the computing zone. This movement is preferably controlled by the movement of the column-totalizer, which is usuall' also carried by the typewriter carriage, or vertical com utation.

Smce the stops may be all alike, the still greater advantage "is gained of utilizing a key-set 't-abulator mechanism, in which the stops (one of which is provided for Bilk'll letter-space of the typewriter carriage) are settable by a key arranged at the keyboard of the machine. The position of the carriage determines which stop shall be sci. in order to set these stops, the operator first positions the typewriter carriage at the desired point, and then depresses the key for setting the stops.

According to this invention, a cam carried by said (-olumn-totalizer may, as a computing zone is approached, cause the conne tions from the cross-totalizer to be moved up into position to be engaged by one of the carriage tabulator stops that has been keyset in the described manner. The crosstotalizer is then advanced by the typewriter carriage until the latter passes out of the computing zone, at which time said cam on the column-totalizer may cause the connectionsto move away from the tabulator stops. The cross-totalizer and its connections return to normal positions. This operation may be re ated at each computing zone.

Hereto ore, in some instances, the crosstotalizer has been reciprocated by a (llltwt connection to the column-totalizer, but it has been found that the column-totalizer should not be thus burdened, as it is a very sensitive part of the machine. This difii'eulty is overcome by my invention, since the cross-totali'z'er may be reciprocated by tabulator stops which are or may be universally alike. A more rigid and less sensitive part of the carriage mechanism serves to move the crosstotalizer, although the present invention maintains the control of the cross-totnlizer from the column-totalizer, inasmuch as the column-totalizer simply moves an interpon'ent which causes the cross-totalizer to be moved by the typewriter carriage. It will be seen, therefore, that there are two important features included in the present invention, first to cause the cross-totalizer to be. moved by the tabulator stops of the typewriting machine, under the control of the column-totalizer, and second, that a key-set decimal tabulator may advantageously be used for reciprocating the cross-totalizer.

The operator sometimes desires to compute in the column-totalizer without computing in the cross-totalizer; and for this purpose the train of connections between the columntotalizer and the connections from the crosstotalizer ma be broken at the will of the operator. his may be accomplished by mountin the cam on the column-totalizer so that it can be moved at will out of the range of the follower.

This invention is illustrated in connection with the disclosures of my application No. 112,645, filed August 2, 1916, and Pitman applications Nos. 24,390, filed April 28, 1915, and 186,098, filed August 14, 1917.

Other features and advantages may hereinafter appear.

In the accompanying drawings,

Numeral keys 1 and a1 habet keys 2 depress key levers 3 to rock ell cranks 4, so as to swing type-bars 5 up rearwardly against the front side of aplaten 6 mounted to ro tate on a carriage 7. The carriage 7 ,travels step by step under the control of anescapement mechanism, which. includes a rack bar 8 pivotally mounted on the carriage 7 and normally engaging a pinion 9. The pinion 9 is connected by the usual one-way pawland-ratehet mechanism, not shown, to an escapement wheel 10, which is controlled in. its movements by fixed and loose dogs 11. and 12. The dogs 11 and 12 are rocked into alternate engagement with the escapement wheel 10 at, each operation of a character key, by means of a universal frame 13, which,

in turn, is operated by heels 14 provided on each of the type-bars 5.

In addition to step-by-step letter-feed movements, the carriage 7 has jump or tabulating movements to skip from one major column or zone to another major column or zone. For this purpose, there is provided tabulatin mechanism, which includes decimal tabu ating keys 15 connected in a manner common to Underwood standard type- P writers, to thrust plungers 16 up into the path of set stops 17 carried by the ty cwriter carriage 7. The tabulatin mec 1anisin is of the key-set type in which there are provided a series of identical stops 17, one for each letter-space of the typewriter carriage 7. These stops 17 are normally held in a raised inactive osition on a bar 18, carried by the carriage by spring-pressed detents 19. The stops 17 are settable indi viduall by bringing the typewriter carriage to the otter-space at which it is desired to have a major column or zone and then dopressing a setting key 20. This setting mechanism is more particularly described and claimed in the patent to Deane No. 1,157,683, patented October 26, 1915. The action of this key-setting mechanism consists in do pressing the key 20 to rock a key lever 21 which thrusts down on a link 22 to rock a bell crank 23. The bell crank draws down on a setting link 24, which has an overhang 25 projecting over the series of stops 17 corresponding to the printing point of the carriage 7. This overhang 25 depresses the particular stop 17 corresponding to the bringing of the required zone or major column to the printing point of the typewriter. The.stops 17 are of uniform character and may determine solely typewriting zones or combined typewriting and computing zones in a manner more fully described hereinafter.

Considering the computing mechanism, the numeral keys 1, in addition to printing the digits, may also compute them and run them up into totalizers or computing units. These computing units include one or more vertical adding heads 26 and one or more cross-adding heads 27. The vertical adding heads 26 form the traveling elements of the vertical column-computing units and are adjustably mounted along a rail 28 connected by a bracket 29 to travel with thetypewriter carriage 7. These vertical adding heads 26, by their adjustment on the rail 28, can be made to correspond to any desired roup of letter-spaces or digit columns of t ie typewriter carriage 7, and thus with any desired major column or computing zone of the typewriter carriage 7. The adding heads 26 travel step by step with the carriage 7 when in a computing zone relatively to a master wheel 30. The master wheel 30 is driven from the numeral keys 1 by a key-drive valuating or indexing mechanism in a manner emma more particularly described in applications Nos. 24,390 and 186,098, above mentioned. Similarly, the computing wheels of the crossadding head 27 are driven by a master wheel 31, which is also connected to be simultaneously driven with the master wheel 30 by the numeral keys 1.

The adding head 27, which forms the traveling element of the cross-totalizer or computing unit, is not directly connectedmo travel with the typewriter carriage 7 as are the vertical adding heads 26. This traveling element of the cross-totalizer is connectible indirectly to travel with the carriage 7, so as to move intermittently with the carriage 7 and with the vertical adding heads 26. In this way the cross-computing unit can compute in individual synchronism with several of the vertical column-computing units,-with either, all, or some of them.

Considering this traversing mechanism for the traveling element ofthe cross-computing unit, the crossadding head 27 is adustably mounted on a computing carnage 32, which may be connected to be advanced and returned by a bell crank 33, which may be operated to rock about a vertical axis by a lever 34. The lever 34 may be connected to be operated by a. hook 35, and the hook 35 may be icked up by certain of the set stops 17 and traversed step by step with the advancing movement of the carriage 7. This train of connection, including the parts 33, 34 and 35 may act in an advancing direction against is e tension of a spring 36 which quickly returns the traveling element 27 when the hook 35 is disconnected from one of the stops 17 which picked it up.

'Normally, thehook 35 is in a depressed position out of reach of all of the stops 17, even those which are set to determine major column or zonal positions of the tygiewriter carriage 7. To bring this hook 3 within range or reach of certain ones of the set stops 17, each of the vertical column-adding heads QSis provided'with-a synchronizing cam 37 which determines theeomputing activity'cf the cross-adding head 27. The cam 37 is in" the form of a rail having a length greaterthahthe number of digit columns in a computing Zone; and also weare than the number of foiiiputing wheels of different denominations in the cross-adding head-27,"so that the hook 35 may be in a raised position to be :engagedby a stop lf'i'flin advanee=bf the {lines inggof the competing wheel of highest denomination with the masterwheel.

As the carriage 7 advances in a letter-feeding direction, on entering a computing zone,

the cam rail 37 when in an active position,

enga' es" a one-Way acting dog 38 pivotally mouhfied on Fa slid 39 and depresses the same'so as torcck a lever lth *Thedever 4O i'j'eoii ect'edto' {n11 a one Eskimo asto ro'c'ka {ever 4 "a e nmdhe tensien of a spring43. The lever 42 rocks another lever 44, which thrusts upwardly on a shifter 45. The shifter 45 is in the nature of a sl d guided for vertical movement by pins and slots 45, and is provided at its upper end. with a head 47 having a slot 48 of at leas the capacity of the number of letter-spaces or digit columns of a cross eomputing zone. The hook 35 has a pin 49 extending into the slot 48, so that when the cam 37 on the vertical adding head enters a computing zone, in which it is desired to have a cross-computationthe shifter 45 will raise the hook 35 into the path of the particular set column stop 17 corresponding to this zone. This stop willcarry the cross-computing traveling element 27 step by step in an advancing direction with the advancement of the typewriter canriage 7 through the computing zone. Thus, the traveling element 27 of the cross-computing unit will advance in synchronism with the letter-feed movements of the carriage, and also with the step-by-step movements of the traveling element of the vertical column'totalizer or computing unit which controls the cross-computing units coming into play. This enables a coneomi taut computing or cross-adding with a verti cnl adding as the digits are typewritten.

When the end of a computing zone is reached, the end of the cam rail 37 will come in register with the one-way acting dog, so that the spring 43 may act to return the slide 39 to a raised position and the shifter 45 to a depressed: position. This will withdraw the hook .35 out of engagement with the zone-controlling stop 17 which carried it along up to this time, so that the hook 35 is free to return relatively to the typewriter carriage 7. The return movement is accomplished by the spring 36 which also returns the cross-adding head 27, which happens to be the traveling element to its starting position.

For an advancing movement of the carriage 7,during the writing of a continuous line, the crossmdding lhead =97 will be moved at tlmes in synchronism with i the typewriter carriage 7 for-difierent; computing zones, ac- 'cording to thennmberbf the vertical adding Heads-'26 which have aotivecams 37 thereon. The return movement of the. typewriter carriage *7 1does' not vibrate the cross adding head 27:.asthe cing-38', which is one-way acting, rocks idlyabout its pivot when one of the active cams 37 passes over it in a return direction. This dog 38 is. held by a spring oo against a pin 51, so that the dog is permitted to rock-idly when the typewriter carriage end'zviertioali adding heads 26- pass by it in a return direetiomhut an active posltion'of thedog 381is insured when the typef. writer carriage moves in an ,advaneing direetibm '1 a i:

In some zones in which itiiis; desired to compute in the vertical computing units, it is not desired to also compute in the crosscomputing unit; hence the cams 37 are made adjustable between active and inactive positions, so that selective action of the crosscomputing unit can be had with respect to the individual vertical computing units. For this purpose. the :am 37 is provided with arms 52, which are slidably mounted by means of pin-and-slot comiections 53 on each vertical adding head 26. The active and inactive positions of the cam rail 37, ineach case, are determined by a spring detent 54 which engages alternately in notches 55 and 56 provided on one of the arms When the controlling element, including the cam rail 37 and the arms 52, is pulled to its forward position by a handle 57, as indicated by dot-anddash lines in Fig. 1, the cam rail 37 will be in an inactive position as its line of travel will be out. of register with the dog 6H. \Vhcn in its rear position, theline of travel of the cam rail 37 will be in register with the dog 38. so as to be capable of operating the connection and disconnection of the cross-adding head 27 of the typewriter carriage 7.

Considering briefly the operation of the device. it may be assumed that the machine is ready for a new type of work with all of the stops 17 in their unset position. The

'l'ypewriter carriage 7 is positioned zone by zone to correspond with the active major columns of the particular character of Work which it is desired to typewrite and compute. The vertical column-adding heads :26 are adjusted along the rail 28 to posi tions corresponding to certain of the zones determined by set ones of the stops 17. This need not be all of the zones, as some of the zones selected may be for the purpose of typewriting solely. As the carriage is positioned in each zone. the tabulating stopsetting key it) is depressed, so as to set the stop 17 corresponding to the lowest denominational position of this zone or major column. This stop will subsequently, through the cooperation of the tabulating mechanism 15, 16, determine the rapid selection of zonal positions of the carriage 7 For such of the computing zones as the vertical adding heads 26 are set, it may also be desired to simultaneously cross-add the numbers run up into these vertical adding heads, whereas, in certain other computin zones, it may be desired that the cross-adding head 2; shall remain silent. For such computing zones as it is desired to have concomitant vertical and cross-adding, the synchronizing rails 37 are shifted to their rearmost active positions. In such computing zones as it is desired to have no cross-adding, the rails 37 on the correspondin vertical adding heads 36 are shifted to t eir forward inactive positions.

5 writer carriage 7.

The carriage i' is then positioned for the initial zone or major column by striking one of the decimal tabulating keys to. which will raise one oi the plungcrs lo into the path of the first sci; stop l7. The carriage 7 will amp to the first zone which is determined by the first set stop 17, striking the raised plunger .16. This zone may be solely for the purpose of typcwriting, such as writing the date or the character of the item. If such is the case. there will be none ol' the vertical adding beads :26 located on the rail in mrrrsponding to this zone: hence. there will be no \ei'tical computing. and. inasmuch as the cams 3T controlling the crossron'iputing are on the Vertical adding heads. there will also be no t'l't)S i CHlllplltllll.

1hr typewriter carriage 7 may then he jumped to the next zone after the typewrit ng for the first zone has. been accomplished step by step, by striking one of the labulating keys This will select a particular letter-space or digit column in the next zone. This zone may be solely for the purpose of vertical computing. If so, the rail is in its forward or inactive position. T he digits will then be run up solely in the vertical adding head 26, corresponding to the particular computing zone.

The carriage 7, after the digits of this computing zone have been typewritten. may be jumped to the next zone by striking one of the tabulating keys l0. This next. zone may be for both vertical computing and cross-computing. If such is the case, the cam 37 on the vertical adding head will be in its active position. As the typewriter carriage 7 comes into this computing zone, the rail 37 will cause the picking up of the cross-adding head 27, by engaging the dog 38 to depress the slide 39. and thus, through the connecting train of linkages, raise the hook 35 in the path of the stop 17 corresponding to this combined ty ewriting and computing zone. At the striking of the numeral keys to write and compute in this zone, the cross-adding head 27 will advance step by step in synchronisrn with the typewriter carriage 7 and with the particular vertical adding head 26 which controls its bringing into play. with the striking of the numeral key correspondin to the writing and computing in units 1) ace, the digit of this place will be typewritten and run into the units computing wheels of both a vertt cal column-adding head 26 and the crossadding head 27. As the typewriter earriage 7 advances at the return-stroke of the numeral key, this will clear the cam rail 37 f-F Ol'll engagement with the do 38, causing the hook 255 to be withdrawn irom connec tion with the set stop 17 which has been carrying the hook along with the typewriter carriage 7. With the disconnection of the train of connection to the cross-adding head 27, the spring 36 will return the head to its initial position just out of register with the master wheel 31.

In this way, the complete typewritten and computing line is done, the cross-adding head 27 being picked up a number of times, so as to act in synchronism with several of the vertical adding heads 26. In this way a combined typewriting and computing ac tion can he had, in which the numbers as typewritten are added vertically and also certain of them added horizontally. Also, this action is enabled by a series of u i rm or identical stops 17 which are of a con venient key-set cl'iaractcr and which are uni tormly set. The selection of which ones of the actively set stops shall be the crosscom uting .zone'oontrolling steps is accomplished by the cam rails 37 on the vertical adding heads 26.
